BT103S
The BT103S peristaltic pump is driven by a high-quality stepper motor, with a speed range of 0.1 to 100 rpm and speed accuracy of ±0.2%. Its single-channel flow rate range is from 0.0001 to 480ml/min. The RS485 communication interface, compatible with Modbus protocol, can be connected to computers, microcontrollers, PLCs, inverters, HMIs and other external devices for systematic or centralized control.
Functions and Features
- Membrane keypad operation is convenient and durable.
- High-quality closed-loop stepper motor drive, accurate speed and smooth operation, allowing for high-precision flow transmission.
- Basic functions such as forward and reverse, start/stop, full speed, speed regulation, and state memory (power-down memory).
- Parameters include running time, interval time, number of cycles, etc. to meet the needs of timed dosing, liquid dispensing, and flow testing.
- The slow stop and anti-drip function can effectively prevent liquid dripping when stopping.
- Key lock function to prevent misoperation.
- Streamlined plastic housing, easy to clean.
- Circuit board with layered paint process for dust and moisture-proof.
- Excellent anti-interference characteristics, wide voltage range, suitable for complex power supply environment.
- Various external control signals can be used to control start/stop, forward/reverse rotation, speed adjustment, and optocoupler isolation.
- RS485 communication, compatible with Modbus protocol, for convenient connection with various control devices.
- Support blocking and leakage alarm (optional).
- A thermal printer can be connected for real-time printing of operating parameters (optional).
- Can be connected with a variety of high-performance pump heads.
